Holographic D instanton liquid and chiral transition
We study the phase diagram of black D3 geometry with uniformly distributed D-instanton charge using the probe D7 brane. In the presence of uniform D-instanton charges, quarks can be confined,
On the giant magnon and spike solutions for strings on AdS3 × S3
We study solutions for the rotating strings on the sphere with a background NS-NS field and on the anti-de-Sitter spacetime. We show the existence of magnon and single spike solutions on R × S2 in
A dual geometry of the hadron in dense matter
We identify the dual geometry of the hadron phase of dense nuclear matter and investigate the confinement/deconfinement phase transition. We suggest that the low temperature phase of the RN black
Zero modes and the Atiyah-Singer index in noncommutative instantons
We study the bosonic and fermionic zero modes in noncommutative instanton backgrounds based on the Atiyah-Drinfeld-Hitchin-Manin (ADHM) construction. In the k instanton background in $U(N)$ gauge
Comments on Instantons on Noncommutative R 4
We study U(1) and U(2) instanton solutions on noncommutative R 4 based on the noncommutative version of ADHM equation proposed by Nekrasov and Schwarz. It is shown that the anti-self-dual gauge
Holographic charged fluid with anomalous current at finite cutoff surface in Einstein-Maxwell gravity
A bstractThe holographic charged fluid with anomalous current in Einstein-Maxwell gravity has been generalized from the infinite boundary to the finite cutoff surface by using the gravity/fluid
Supersymmetric Chern-Simons vortex systems and fermion zero modes.
Fermion zero modes around a general multivortex background are analyzed in supersymmetrized self-dual (Maxwell--) Chern-Simons Higgs systems, using the index theorem and other means. In the models
Moduli space dimensions of multipronged strings
The numbers of bosonic and fermionic zero modes of multi-pronged strings are counted in ${\cal N}=4$ super-Yang-Mills theory and compared with those of the IIB string theory. We obtain a nice
Abelian vortices in Bagger-Lambert-Gustavsson theory
Among newly discovered M2 and M5 objects in the Bagger-Lambert-Gustavsson theory, our interest is about ½ BPS vortices, which are described by covariantly holomorphic curves in transverse
Observational constraints on slow-roll inflation coupled to a Gauss-Bonnet term
We study slow-roll inflation with a Gauss-Bonnet term that is coupled to an inflaton field nonminimally. We investigate the inflationary solutions for a specific type of the nonminimal coupling to
